The remains of a medieval "vampire" have been discovered among the corpses of 16th century plague victims in Venice, according to an Italian archaeologist who led the dig.

The body of the woman was found in a mass grave on the Venetian island of Lazzaretto Nuovo. Suspecting that she might be a vampire, a common folk belief at the time, gravediggers shoved a rock into her skull to prevent her from chewing through her shroud and infecting others with the plague, said anthropologist Matteo Borrini of the University of Florence.

In the absence of medical science, vampires were just one of many possible contemporary explanations for the spread of the Venetian plague in 1576, which ran rampant through the city and ultimately killed up to 50,000 people, some officials estimate.
